1) Don't do DNS lookups on the routers in the path (Numeric display
[n]:)

2) Set the timeout lower (Timeout in seconds [3]:)

3) Don't send three probes per TTL (Probe count [3]:)

4) Start with a higher TTL if you know the first few routers in the
path (Minimum Time to Live [1]:)

5) End with a TTL lower than 30 in case the destination can not be
reached but enough to reach the destination if it is reachable (Maximum
Time to Live [30]:)
